Myinvention relates to apparatus forpro ducing motive power used in -con unct1on with gasproducers or oil distilling apparatus. 6 The principal obgect of my mventlon Is -to PIOVIQBJB. means, or recovering the greater portion of the heat which is ordinarily carried away by the gas leaving an appam"ratus of the type indicated.

in which--- The single figure is a diagrammatic view 1 apparatus conforming to my inyenlatinfi supp 'ed under constant pressure to the tur A more specific object. of the invention is to utilize the heat thus recovered for re heating air com ressed by means of a motor compressor 'of t e direct driven direct act'- ing internal combustion type, -more fully described in my prior Patent No. 1,691,737,- of Nov. 13, 1928, which feeds a turbine in such wise that all or a part of. the recovered .heat may be transformed into mechanical work durin expansion of said air thus compressed an reheated.

e Other ob'ects' of theinvention will be obvious to t ose skilled in the art with reference to the following descriptiontaken in connection with the accom anymg drawing of an tion.

Referring-to the drawing, a motor-compressor 10 of the direct driven direct acting internal combustion type, more fully described in my prior patent hereinbefore referred to, feeds a turbine 11 and a gas producer 12 feeds the motor cylinder of the compressor 10 with gas. The compressing cylinders of compremor 10 are connected to a tank 14 bymeans of pipes 20. A pipe line 13 connects. the tank 14 to the turbine 11 and disposed in saidpipe 'line is a reheater 15 w 12 by in said reheaterheats. the air being bine 11. Thesaid gas is 'led through a pipe 17 to the motor; cylinder of compres'sor 10 where it is, consumed in drivingsaid compressor.

' A second reheater'19' is dispos d in s;

pipe line 13..bet ween thejreheater 15' and ,the turbine 11. Said r'eheater isconnected "a portion of the heat in said com ich is connected to the producer means of a pipe 16. The gas circuto the exhaust pipe 18 of compressor 10 in such a manner that the burned gases may 6 pass therethrough and thus further heat-th a r in pipe line 13 being supplied to the turbine '11 under constant pressure. There is thus recovered a certain ortion of the heat in the exhaust gases of t e compressor. The arrows clearly show the direction taken'by the compressed air and that taken by the gases during operation. The air compressed and hence'upon the amount of heat taken on from the gas from producer 12 as well as that from the exhaust 18.

Many variations in my apparatus inay be made by those skilled in the art without departing from my invention,'since What I claim is-- 1'. ,Inzan apparatus of the type described an internal combustion air compressor of the direct driven direct acting type having a main driying cylinder and a plurality of compressing c linders, an air turbine connected 'to' sai compressing cylinders, means for supplying said driving cylinder with a combustible fluid at a temperature greater than that of the air compressed by said compressor and means for im artingi ustible fluid to the air furnished to said turbine for the purpose specified. 2. In an apparatus of the type described an internal combustion aircompressor' of the direct driven direct acting type having a main driving cylinder and a plurality of compressing cylinders, an air turbine connectedto said com ressing cylinders, means for supplyin combustible uid at a temperature greater thanthat of the air compressed b said oompressor, means 'for. expelling't 'e' exhaust gases from said driving 'eylinder, means for sai driving'cylinder with a impartinfi a ortion of the heat in said combustible uid to the air furnished to said turbine and means for imparting additional heat to the .air furnished said turbine from 5 the exhaust gases expelled from said driving 0 linder' for the purpose specified.-

3. in an apparatus of the type described an internal combustion air compressor of the direct driven direct acting type having a main driving cylinder and a plurality of compressing cylinders, a tank connected to I said compresslng cylinders, an air turbine, a p1pe line connectmg said tank to said air .turblne, a plurality .of heat-exchange de-.

vices dlsposed in said pipe line, a gas producer for said compressor, a p1pe connecting said gas producer with one of said heat exchange devices, an admission pi e connecting said driving cylinder with sand same heat exchange device and an exhaust pi e for said drivmg cylinder connected with t e other of said heat exchange devices for the purpose specified.
